The sysstatus command is a system-defined alias for the Linux top command, which displays and
updates information about the top CPU processes. It provides a real-time view of the processor activity.
It lists the most CPU-intensive tasks on the system, and can provide an interactive interface for
manipulating processes. It can sort the tasks by CPU usage, memory usage, and runtime.
To view the current CPU activities, enter:
